What is the Potential Impact of the IsoDAR Cyclotron on Radioisotope Production: A Review [PDF]

EJNMMI Radiopharmacy and Chemistry 5:6 (2020), 2018
The IsoDAR collaboration is developing a high-current cyclotron for a neutrino search experiment. Designed to deliver 10 mA of 60 MeV protons, the current and power of this cyclotron far exceed those of existing accelerators, opening new possibilities for the production of radiopharmaceutical isotopes, producing very high-activity samples in very short

Prostate cancer aggressiveness and financial toxicity among prostate cancer patients

The Prostate, Volume 83, Issue 1, Page 44-55, January 1, 2023., 2023
Abstract Introduction Financial toxicity (FT) is a growing concern among cancer survivors that adversely affects the quality of life and survival. Individuals diagnosed with aggressive cancers are often at a greater risk of experiencing FT. The objectives of this study were to estimate FT among prostate cancer (PCa) survivors after 10−15 years of ...

Application of chiral 2-isoxazoline for the synthesis of syn-1,3-diol analogs

Beilstein Journal of Organic Chemistry, 2019
The asymmetric cycloaddition of TIPS nitronate catalyzed by “Cu(II)-bisoxazoline” gave the 2-isoxazoline product in 95% yield, which was converted into tert-butyl (3S,5R)-6-hydroxy-3,5-O-isopropylidene-3,5-dihydroxyhexanoate in 14 steps through a β ...

A projection-domain low-count quantitative SPECT method for alpha-particle emitting radiopharmaceutical therapy [PDF]

arXiv, 2021
Single-photon emission computed tomography (SPECT) provides a mechanism to estimate regional isotope uptake in lesions and at-risk organs after administration of {\alpha}-particle-emitting radiopharmaceutical therapies ({\alpha}-RPTs). However, this estimation task is challenging due to the complex emission spectra, the very low number of detected ...
